T 0 all 207mm it may concern:

Be it known that I, OLIVER P. TAYLOR, a citizen of the United States, residing at Rockland, in the county of Knox and State of Maine, have invented certain new and useful Improvements in Attachments for Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in attachments for engines and has for its primary object the provision of means whereby moist air can be taken from the radiator of the engine and fed into the intake manifold for the purpose of preventing the accumulation of carbon in the engine, thereby with the substantial elimination of carbon and with vapor mixed with the fuel renders a smoother running engine with a saving of fuel and one with increased power and flexibility.

Another object of this invention is the provision of an air and moisture collecting member positioned in the radiator and connected to the manifold of the engine, so that moist and heated air may be drawn into the engine for mixture with the explosive fuel to reduce the accumulation of carbon inthe engine and to cause a more highly combustible fuel.

A further object of this invention is the provision of an attachment for engines of the above stated character, which shall be simple, durable, and efficient, and which may be manufactured and sold at a comparatively low cost.

lVith these and other objects in view as will become more apparent as the description proceeds, the invention consists in certain novel features of construction, combination, and arrangement of parts as will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a vertical sectional view of an attachment for internal combustion engines constructed, in accordance with my invention and illustrating the same applied to an engine, and also to the radiator thereof,

Referring in detail to thedrawing. I have elected to illustrate my invention applied to an automobile, but, however, the device can be conveniently used in connection with an internal combustion engine fordriving aeroplanes and otherdevices that employ engines for propulsion. The numeral lfin dicates an internal combustion engine having an intake manifold 2 and carried by an automobile 3. Theinternal combustion engine 1 has associated therewith the usual radiator 4 provided with a filling spout 5 and an overflow pipe 6 which'extends from a point adjacent the filling neck 5 to a point at the bottom of the radiator and at this point extends exteriorly of said radiator so as to permit water after reaching a given point within the radiator to pass out of the same and also will permit air to enter the radiator when not draining water therefrom.

The foregoing description relates to a well known construction and to which my invention is applied.

The rear wall of the radiator 4 adjacentits filling spout 5 is provided with an opening 7 in which is positioned an externally threaded bushing 8 which receives a pipe 9 permitting said pipeto extend into the radiator. Vashers 10 are mounted uponthe bushing and are forced into engagement with the wall of the radiator by means of nuts 11. A packing nut 12 is threaded to one end of the bushing 8 and receives the pipe 9 for the purpose of establishing a water-tight connection between the pipe and said bushing. The pipe 9 after extending into the radiator is bent to form a substantial gooseneck shaped portion, 13, the end of which is enlarged to form a fun nel shaped member 14 to which is hinged a strainer 15. The strainer 15 is held in a closed position by a catch 16 and has located therein a float valve 17. The strainer is of substantially conical shape and has its apex formed of sheet metal so as to form a seat for the valve 17 and which seat will prevent the valve from being raised by the suction in the collecting element. The valve 17 is adapted to close the pipe 9 in case the radiator is overflowed with water when filling the same thereby preventing any danger of water from getting into the pipe 9 when not desiring water in said pipe.

A controlling valve 18 has unions 19 and 20 secured thereto and the union 19 has the pipe 9 connected thereto and also has threaded thereon a stufling nut 21 to establish a leak-proof connection between the pipe 9 and the. union 19. The union 20 has secured thereto a pipe 22 which is in turn connected to a nipple 23. A packing nut 24; is threaded to the union :20 and establishes a watertight connection between said union and the pipe 22. The nipple 23 is also provided with a packing nut 25 to establish a watertight connection between the same and the pipe 22. The. nipple 23 is threaded into an opening 26 formed in the intake manifold 52 so that when the valve is in an open position the vacuum created by the suction of the engine will draw air upwardly through the overflow pipe 6 into the pipe 9 also will draw moisture or 'apor into the pipe 9 from the radiator and as the moisture, vapor and air passes into the intake manifold 2, it mixes with the fuel passing through the same and enters the combustion chambers of the engine and on so doing prevents the accumulation of carbon and other foreign matter in the cylinders of said engine.

A rod 27 is pivoted to the handle 28 of the valve 18 and extends through the instrument board 30 of the automobile 3 and also through a dial 31 secured to said instrument board. The dial has printed thereon, certain characters to indicate the position of the valve. A handle 32 is secured to the rod 27 and is provided with a projection 33 adapted to be alined with the various characters so as to assure the opening and closing of the valve.

From the foregoing description taken in connection with the accompanying drawings, it will be noted by regulating the valve the amount of vapor, moisture, and air can be controlled to the intake manifold of the engine and also if desired the engine can be flushed with water from the radiator by first closing the overflow pipe 6 with a suitable plug (not shown) and filling the radiator to its fullest capacity and with the engine in motion and on opening the valve 18, water will be drawn into the manifold and passed into the cylinders of the engine for the purpose of flushing and cleaning the same of any foreign matter that may be in the same.

In order to protect the valve when filling the radiator, I have provided a hub or cover 34 which is positioned over the valve and pipe and within the inlet neck of the radiator.

lVhile I have shown and described the preferred embodiment of my invention, it will be understood that minor changes in construction, combination, and arrangement of parts may be made without departing from the spirit and scope of the invention as claimed.

Having thus described my invention, what I claim is l. A device of the character set forth including an engine having an intake manifold and a radiator having an overflow pipe, a substantially funnel shaped collecting element *arried by said radiator, a strainer for said collecting element, a float valve carried by said strainer and adapted to close the collecting element when contacted by water, a. pipe connected to the collecting element and to the intake manifold, and a valve in said pipe.

2. A. device of the character set forth including an engine having an intake manifold and a radiator having an overflow pipe, a substantially funnel shaped collecting element located in said radiator over the upper end of the overflow pipe, a strainer hinged to said funnel shaped member, a catch securing the strainer in place, a float valve carried by said strainer, a goose-neck shaped pipe formed on said collecting element and extending through the radiator, a valve connected to said pipe, a second pipe connected to the valve, a nozzle connected to the second named pipe and secured in the intake manifold, an operating rod pivoted to said valve and extending through the instrument board, a dial carried by the instrument board and receiving the operating shaft and having characters thereon, a handle secured to said operating shaft, a projection formed on said handle for cooperation with the characters on the dial.

In testimon whereof I aflix my signature in presence 0 two witnesses.
